Topic: central air cool not cold (Read 4980 times)

i have a residensual home with a new arcoaire unit out side. the unit in the attic is from 1998 .the out door unit has checked two times and is charged . the air coming out the vents is about 68 70 degreces. the tech said he'd like to see it at 59 or 60 .could it be bad or dirty ev coils or could the coils be bad.

to niobrara : soon as it's cool enough i'm going to chek and clean ev coils.the outside unit model is arcoaire #R2A330GKC1 . the attic unit is from 1998 comfort maker model # EXM36F19A1 . don't know what 410 or 22 coil is. soon as ido this i will post . TO JUMPTROUT51:i'll check and clean what i can. to jwwebster:your answer is obviusly for a tech. i'll do what i can .then i'll post . what is the a coil ? i hope to get to this this week so i will be posting. thank's for the reply.

to all: i'm not a tech so superheat and such i can't test.what i did today is tape up two small openings in the duct that goes into the air handler unit where the a- coil resides. i didn't compare temp output from room ceiling vents. but it seems a little better than yesterday. i'm in trenton nj. so were in a heat wave . the attic is around 110 112 degrece. friday morning i hope to take off the panel to get to the a- coil. i'll spray it with the coil cleaner and flush with hose. my next move i'm thinking i'll wrap the whole condesing unit with visquen plastic and tape.this could take a while ? i'm going to do the jumpp trout stuff first. as for jwwebster i'd need a tech for those kind of test. TO JWwebster im not to yours yet but how do you adjust the a- coil ? would that be by adding or taking out the freon charge ? back tomorow hopefully.

If you want the system tuned properly so that the new condenser matches the old air handler you gonna need to check superheat and subcooling to see what is going on with it. Here is Dr Z with a nice Video:

Get you some NO RINSE coil cleaner. Remove as much of the lint, hair, and dust you can with a soft bristle brush. Go by directions on can. Basically you turn off the system. Apply the spray. Let it foam up and pull out deep down grime. Be ready with towels if you do not want it to go everywhere. Wait 10 minutes then turn the unit back on. The foam will go down the drain and clear it out also. Go by directions on can. Get it online or at an HVAC distributer near you.
